ARP attack fault in wireless router settings

How to effectively eliminate attacks in a wireless LAN is the capability of network administrators or technicians. This article will detail how to prevent ARP attacks.

With the rapid development of social information technology, enterprise network-based office has now entered the wireless network field. The biggest advantage of building a wireless network is that the network is easy to use and cost-effective without wiring. Therefore, most enterprises are undoubtedly the best choice for networking solutions. A large number of wireless routers are used in enterprises, making Fault Diagnosis and security assurance for wireless networks as important as wired networks.

In enterprise wireless networks, there are often some user manuals that do not involve any problems or faults. Sometimes they are hard to cope with and cannot be solved. Next, I will analyze the typical faults caused by routers in wireless networks and provide solutions.

Connection error line failure in wireless router settings

There are many reasons for the disconnection of network lines, but the first thing to check is whether there are errors in the connection configuration.

Check the broadband access end before the router power supply is normal. The indicator lights on the vro can indicate whether the broadband line access end is normal. In the instruction, you can identify which light is the broadband access end and the user end, and observe whether the light is shining, if the light is not bright or the light is not blinking, It is a fault. We can change a broadband cable to replace the original line for connection.

If the fault persists, check whether the router is placed too far from the receiving computer or there are large obstacles in the middle. In this case, re-place the router so that the wireless router and the receiving computer do not have too many obstacles, and make the receiving computer within the signal transmission range of the wireless router.

Wireless Nic check is also essential. You can replace the New Nic and reinstall the driver for debugging, click "view available wireless connections" in the NIC to refresh the "Network List" and set the NIC parameters. Then, click "properties" to check whether data is sent and received, and troubleshoot the problem.

Of course, the hardware fault of the router itself is also the direct cause of line failure, but this is not the scope we can solve, we should contact the manufacturer for repair or replacement in a timely manner.

The wireless router cannot be connected due to improper configuration.

"Settings" can be divided into two aspects: computer settings and router settings.

The computer settings are relatively simple. Click to enter the "Network Neighbor" attribute, enable "wireless network connection", and then set "ip address", "subnet mask", and "Gateway ", you only need to make the IP address of the computer and the IP address of the wireless router in the same network segment. For more information about how to set the "Gateway", see the NIC description. Generally, it is the same as the IP address of the vro.

Vro settings are relatively professional and complex. First, enter the IP address of the wireless router in the system browser, and enter the administrator login name and password of the router in the pop-up logon interface to enter the configuration interface. In this case, you need to check whether the broadband account and password provided by the network service provider are correct. If not, correct the password and try to connect, if the page still cannot be opened after connection, click the "Security Settings" option in the vro to check whether the "Network Firewall", "ip address filtering", and "MAC address filtering" options are enabled, correct and configure the settings to eliminate the failure of enabling the network.

Network attack caused by wireless router settings

ARP attacks and unauthorized intrusion into wireless LAN are now a typical case of network exceptions. Due to the negligence of security settings and the lack of security protection in the future, a few malicious hackers have caused great harm to the important information and confidential data of the enterprise.

ARP attacks may cause network IP conflicts, data loss and overflow, and even worse, network paralysis. These phenomena pose a great threat to enterprise networking.

First, go to "security mode with network", replace the IP address of the computer in the wireless Nic attribute, and then check whether the network can be connected. In addition, purchasing and installing professional anti-virus software and network firewall is one of the shortcuts.

Next, go to the "Security Settings" option of the vro for advanced settings. Most wireless routers now use the WEP password encoding function. They use the Password Key of up to bits to encode the data and communicate with each other on the wireless router. The password key length can be 40 bits or bits, MAC addresses and preset network IDS can be used to limit which wireless network adapters and Access Points can access the network, ensuring network security. For illegal reception, it is very difficult to intercept the wireless network signal, which can effectively prevent hacker intrusion and damage and illegal user malicious network attacks.

Note that you cannot enable "remote WEB Management" in the vro without special requirements or professional skills.

Some router functions in wireless router settings fail and cannot be used

Most of this problem exists in some old wireless routers. When we configure advanced router functions, some functions cannot be enabled when we confirm that the connection is correct repeatedly, at this time, you may first think about whether the hardware is faulty.

First, check the version of the vro system. After reading the wireless router specification, check whether this function supports the vro system of this version. Vro systems usually have many versions, each of which supports different functions. If your current software version does not support this function, you should find the corresponding software and upgrade it first.

Click the "System Tools" option of the wireless router and select "software upgrade". The current software version and hardware version are displayed in the dialog box, in the displayed dialog box, enter "file name" (that is, the name of the system upgrade file) and "TFTP Server IP Address" and click "Upgrade.

When upgrading a vro, be sure to select the software that is the same as the current hardware version. Do not turn off the power of the vro during the upgrade. Otherwise, the vro will be damaged and unavailable, when the network is stable, the upgrade process is very short and the entire process will not exceed one minute. When you find that the router is restarted after the upgrade, Do not worry that this is normal. Generally, after the upgrade, the router will work more stably, and some new features are added for this version.
